Best way to clean electrical contacts?

[Dean85GT]

Whats the best way to clean an oil soaked contact without doing any damage (or any more than what may have already been done). Normally I would just use contact cleaner and/or dielectric grease but this is different. Will a wire brush cause damage. Whaddya think before I go **** up some wiring.

Radioshack Electronic Cleaner, just spray it on and let it air dry.

Well I figured out the problem. The wires that go into the connector and then the ignition box were the culprit. Now I am very aware of the previous owner's hack job wiring. I already rewired the dash and interior. So the 4 wires off this connector were stripped and half covered in electrical tape that was falling off and the wires were covered in oil. Unreal. I just ripped all the **** off cleaned the wires, retaped them took the heat gun to them and cleaned it all up. The car is fine now.
